What does it take to make a sports bar? Many television sets, of course, all tuned to an all-sports station that features either games or loud conversations by groups of former athletes forever interrupting one another or questioning someone’s manhood -- maybe both at the same time. And what about a sports bar and grill, like Lester’s in the Central West End, just east of the intersection of Euclid and Maryland? Does the addition of “grill” mean better meals, or just more toasted ravioli, burgers and chicken wings?
